Abstract: A nozzle for a fan assembly includes an air inlet, an air outlet, an interior passage for conveying air from the air inlet to the air outlet, an annular inner wall, and an outer wall extending about the inner wall. The interior passage is located between the inner wall and the outer wall. The inner wall at least partially defines a bore through which air from outside the nozzle is drawn by air emitted from the air outlet. A flow control port is located downstream from the air outlet. A flow control chamber is provided for conveying air to the flow control port. A control mechanism selectively inhibits a flow of air through the flow control port to deflect an air flow emitted from the air outlet.

Abstract: A nozzle for a fan assembly includes an air inlet, an air outlet, an interior passage for conveying air from the air inlet to the air outlet, an annular inner wall, and an outer wall extending about the inner wall. The interior passage is located between the inner wall and the outer wall. The inner wall at least partially defines a bore through which air from outside the nozzle is drawn by air emitted from the air outlet. The air outlet is arranged to direct air over an external surface at least partially defining the bore. A flow control port is located downstream from that surface. A flow control chamber is provided for conveying air to the flow control port. A control mechanism selectively enables a flow of air through the flow control port to deflect an air flow emitted from the air outlet.

Abstract: There is provided a nozzle for a fan assembly. The nozzle comprises an air inlet, a first air outlet for emitting an air flow and a second air outlet for emitting an air flow, the first and second air outlets together defining an aggregate air outlet of the nozzle, a single internal air passageway extending between the air inlet and the first and second air outlets, and a valve for controlling an air flow from the air inlet to the first and second air outlets. The valve comprises one or more valve members that are moveable to adjust the size of the first air outlet relative to the size of the second air outlet while keeping the size of the aggregate air outlet of the nozzle constant, and wherein the air outlets are oriented towards a convergent point
